Answer 1

3a)3+2/5=15/5+2/5=17/5
  b)5-3/4=20/4-3/4=17/4
  c)3/2+3/4*1/2=3/2+3/8 = 12+3 /8 = 15/8
  d)1/2*1/4=1/8
  e)1/2 + 6,5= 0,5+6,5=7
  f)3,25-3(1,7-3/2)=3,25-5,1+4,5=2,65
  g)5/2+3²*0,25=5/2+9*0,25=2,5+2,25=4,75
  h)3/4-(2/5)² = 3/4 - 4/25 = 75-16/100=59/100=0,59
  I)0,(4)+1/9*5=4/9+5/9=1
  j)0,75+0,08(3):1/6=0,75 + 83-3/900*6=0,75+480/900=0,75+48/90=0,75+24/45=0,75 + 8/15 = 75/100+8/15 = 3/4+8/15=45+32/60=77/60
 k)0,6+3/5*10/12+1/2*4/10=6/10+60/30+4/20=3/5+1/2+1/5=6+5+2/10=13/10
